IMPROVEMENT IN CAR-AXLE LUBRICATORS.

Specification forming part of Letters Patent No. 123,865, dated February20, 1872.

To all whom it 'may concern:

Be it known that I, WALTER P. BURnow, of Norfolk, in the county ofNorfolk and State of Virginia, have invented a new and valuableImprovement in Car-Axle Lnbricators; and I do hereby declare that thefollowing is a full, clear, and exact description' of the constructionand operation of the same, reference being had to the annexed drawingmaking a part of this specification and to the letters and figures ofreference marked thereon.

Figure l of the drawing is a representation of a vertical transversesection of my invention. Fig. 2 is a side elevation of one of thewick-tubes.

This invention has relation to car-axle lubricators, and consists in theconstruction and novel arrangement of wick-tubes containing oilwicks,Which serve to conduct oil from the oil-box to the journal of the axlein order to provide continuous lubrication,substantially as hereinafterdescribed.

' In the accompanying drawing, A represents the 'journal of a car-axle;B, the journal-box or housing; and C, the journal-bearing. The lowerpart of said housing or box is adapted to contain a supply oflubricating oil. D designates wick-tubes, which are in width equal ornearly equal to the length of the journal. These tubes are short andiiat, and their upper ends are beveled downward and inward, as shown. Edesignates standards or legs attached to the back part of each tube. Fdenotes the wicks, of sufficient bulk to completely ll the tubes, andheld in place by means of studs projecting from bars G, which are hingedto the inner faces of the tubes. The studs are marked g, and passthrough holes g formed in the tubes. The bars G are notched at h, andareprovidedwith handles, h1. Springs h2, secured to the wick-tubes,press against the bars G with sufficient force to keep the studs g inthe wicks.

When the wick is to be raised or newly inserted, the bar G is raised.Thereupon the springs h2 enter the notches h and hold the bar up. Thewicks are to be put in the tubes through the lower ends thereof, anddrawn above the upper ends sufficiently to bring them into contact withthe surface of the journal. The upper ends of the wicks should be thenclipped off so as to make the surface coincide with the bevel of thetubes, or with the rounded surface of the journal. This clipping,however, may be dispensed with without greatly interfering with theutility of the invention. The tubes are so placed in the housing or journal-box as to lean toward the opposite sides of the journal. Thisinclination is the result of placing the legs E in the corners ofthebox, as shown in the drawing. The weight of the inclined tubes will thuscause them to bear against the journal with sufficient force to spreadthe wicks and produce an even lubrication.

The oil-box will seldom require replenishing. The only material wastewill result from evaporation and from the accumulation of metallicdeposit. A clean lubrication is always insured, as the wicks obtaintheir supply from the surface-oil.

I claim as my invention- 1. The combination of the oil-box B, wicktubesD, having perforations g', legs E, hinged bars G, studs g, springs h2,and wicks F, substantially as specified.

2. The combination, with the perforated wick-tubes D, of the hingednotch-bars G and springs h2, substantially as and for the purpose setforth.

3. The wick-tubes D, having the supports E, and arrangedwitli theirbeveled ends inclined toward the journal A, substantially as and for thepurpose specified.

In testimony that I claim the above I have hereunto subscribed my name nthe presence of two witnesses.
